I want to trim any whitepace and check if it is empty in the same line this is not working. if (empty(trim($_POST['_createcategory']))) {

You can't do this because empty needs the variable - it can't work on teh return value. The closest you can get would be... if (isset($_POST['_createcategory']) and

    strlen(trim($_POST['_createcategory'])) > 0) {

Not as neat, but it does the job. You could also do something like this... $_POST['_createcategory'] =

    isset($_POST['_createcategory']) ?
        trim($_POST['_createcategory']) : '';

if (empty($_POST['_createcategory'])) { Still not pretty but slightly better in that you can cleanse your data before you hit logic. -Stut
